Yes, dianthus would work fine in a planter, as long as it has drainage holes. I’m not sure what Zone you’re in so I can’t say for sure what would work for you, but maybe Coreopsis, lamiums for colorful foliage, or try annuals that reseed.

You should be able to feel of the soil and see how long it’s staying wet after watering or rain, make sure there’s no standing water. If the area has poor drainage, you can improve that by amending the soil with compost, add two or three inches and work it in with a shovel.

Good luck! And don’t feel bad about assasinating plants, we all do it. I kill a few every year. :)

It’s the common sweet potato a food crop in the tropics and sub-tropics. After the season you can dig up the tubers and eat them or try and save them for next year, this is a bit tricky like storing potatoes, they tend to shoot and shrivel but possible.

They wont survive in the ground under about 10%c and it must be dry, wet icy soil will rot them. I haven’t seen this variety before usually its dark purple/black or bright yellow/green. This one is very attractive more reddish pink, would look good itself with the very dark leaved form or other such foliage or the other way with silver. The purple petunias do look good, white flowers or variegation would also look stunning.

You can experiment with super market ones found in the veg section. The deep violet fleshed slim ones from Japan come up dark black, the orange large ones are usually plain green I haven’t tried the yellow ones.
